fix(npm): update to npm 3.10.2 (#1250)

The npm task from our current ember-cli install uses npm 2.x.x, which was causing issues with some of the dependencies.

This PR copies over all files needed for the npm-install task but uses a local 3.10.2 npm version instead.

Fix #1186 (main issue)
Fix #1191
